⸻⭐️⭐️⭐️⭐️⭐️ Excellent Lens Mount Adapter – Works Perfectly!I received the Lens Mount Adapter EF-EOS R right on time, and it arrived in perfect condition. The packaging was secure, and the product feels well-built and durable. It fits seamlessly between my EF lenses and EOS Rp body, with no issues at all. Autofocus and image quality are just as expected—no lag or degradation. Definitely a reliable and high-quality adapter for anyone looking to use EF lenses on an EOS R camera. Highly recommended!

I was on the fence about what adapter to get to go with my R7 camera. Canon branded ones are very expensive. Some of the 3rd party ones have reviews mentioning poor fit or quality, or in the case of the Neewer, it drains your battery while connected, even if your camera is off. I decided to go with this one as most of the complaints were about it being too tight, rather than too loose. That sounds preferred to me. The battery concerns on the Neewer steered me away from any model that had the control ring as it seems like any of those could have some sort of firmware problem causing that kind of bad behavior.This adapter feels well built. It is slightly stiff to turn, but to me it feels like it is just a result of a gasket compressing, which should be a good thing, indicating it is weather sealing well. Every lens I tried it with worked- the Canon 17-40mm F4L, 100-400mm f4-5.6L (mark I), Tamron 28-75 XR Di f2.8, Canon 100mm F2.8L Macro.All in all 5 stars. Much better deal than the overpriced Canon models.UPDATE: I had a chance to use this a bit more with the Tamron 28-75 f2.8 and got mixed results. A lot of the images were soft, and I can't tell why. It generally appears to be motion blurring problems. This isn't a stabilized lens, but based on focal length and shutter speed it would appear that the in-body stabilization is not working with this combo of lens and adapter, or else it is not working well. I was mostly shooting at 1/160 and 1/200 which shouldn't be too hard to get sharp photos handheld at 28mm. I compared one scene that I shot with the Tamron at 28mm handheld at 1/60s and with the new Sigma 10-18mm f/2.8 RF (without adapter) at 14mm 1/80s and it was a night and day difference. The Tamron/adapter shot was super soft and the Sigma was tack sharp. Neither of these lenses are stabilized. As I don't know if this is a lens problem, adapter problem or camera problem, I am not taking a star off for now. As I experiment more, maybe I will be able to narrow down what the problem is or see if I have similar results with other lenses. For now, beware if you plan to use this adapter/lens combo.

Great adapter but for some reason when it came in the mail the box had this grease like substance all over it. Other than that it works perfect and very grateful for the price! Very solid and tight and secure fit.

This Standard Mount Adapter is a great solution for using EF/EF-S lenses on Canon EOS R series cameras. It delivers fast auto-focus, precise aperture control, and effective image stabilization. The dust and water-resistant seal adds durability, and the solid metal construction feels premium. At just 145g, it’s lightweight and easy to carry, while the built-in tripod mount is a practical addition. EXIF data transmission works flawlessly too. Highly recommended for seamless compatibility!

I own a canon r10 and this adapter worked perfectly. Auto focus was on the spot. Great for a cheaper alternative to the normal canon adapter!

Great solution when going from mirror to mirrorless camera and converting existing lenses.

The one to buy. The aluminum is polished so it fits nice and snug. I have also purchased a competitors version which was not polished and a little more difficult to attach. Both items were the same price make sure you choose one that has the aluminum polished for a good fit.

Love this very strong and sturdy! Easy to attach to camera and carry around! Always have it on auto focus so works great for me! It came in very quick within 2 days
